Hi, I was wondering if anyone can tell me which slot on the needle valve the clip should be in on a stock 66 cc engine? Also how many turns should the idle screw be screwed in to get an approximate idle? Thanks

I start where the needle is from the factory, then if it seems to 4-stroke on hills (after running in a bit), I'll start moving the clip up to let the needle hang lower.

Sounds good, but the clip wasn't on the needle.

Try the second from the top! That is where I run mine, it is still to rich, but the top one is to lean. Richer is better then to lean.
The idle screw is some where about four truns out from all the way it. Do not screw it in real tight, just easy screw it in until it stops then back it out three or four truns and see how it runs. Then you can fine tune it from there. Hope this helps you.
Keep looking up! Ken.
